My Vinvention relates to an y improvement in a machine for reaming and.lfacinggthe bushings of steering spindlesof 4motor vehiclesjand has amongitsobjeets the produ'c-y tion ofV a device ofthe'kind'described, whichis simple, convenient, compact, durable, re'"` liable,- efficient" andsatisfactory for use f wherever found applicable,
